Also in these examples of the lighting system, the second lighting module includes a second housing and has a second semiconductor light-emitting device in the second housing, the second lighting module being pivotally connected at a second pivot axis by a second pivot joint with the second end of the mounting body.

In further examples, a lighting system is provided herein that may further include: a first connector body having a first end being spaced apart along the first pivot axis from a second end, the first end of the first connector body forming a part of the first pivot joint, and the second end of the first connector body forming a part of a third pivot joint having a third pivot axis; and a third lighting module including a third housing and having a third semiconductor light-emitting device in the third housing, the third lighting module being pivotally connected at the third pivot axis by the third pivot joint with the second end of the first connector body.

The following definitions of terms, being stated as applying “throughout this specification”, are hereby deemed to be incorporated throughout this specification, including but not limited to the Summary, Brief Description of the Figures, Detailed Description, and Claims.

Throughout this specification, the term “semiconductor” means: a substance, examples including a solid chemical element or compound, that can conduct electricity under some conditions but not others, making the substance a good medium for the control of electrical current.

Throughout this specification, the term “semiconductor light-emitting device” (also being abbreviated as “SLED”) means: a light-emitting diode; an organic light-emitting diode; a laser diode; or any other light-emitting device having one or more layers containing inorganic and/or organic semiconductor(s). Throughout this specification, the term “light-emitting diode” (herein also referred to as an “LED”) means: a two-lead semiconductor light source having an active pn-junction. As examples, an LED may include a series of semiconductor layers that may be epitaxially grown on a substrate such as, for example, a substrate that includes sapphire, silicon, silicon carbide, gallium nitride or gallium arsenide. Further, for example, one or more semiconductor p-n junctions may be formed in these epitaxial layers. When a sufficient voltage is applied across the p-n junction, for example, electrons in the n-type semiconductor layers and holes in the p-type semiconductor layers may flow toward the p-n junction. As the electrons and holes flow toward each other, some of the electrons may recombine with corresponding holes, and emit photons. The energy release is called electroluminescence, and the color of the light, which corresponds to the energy of the photons, is determined by the energy band gap of the semiconductor. As examples, a spectral power distribution of the light generated by an LED may generally depend on the particular semiconductor materials used and on the structure of the thin epitaxial layers that make up the “active region” of the device, being the area where the light is generated. As examples, an LED may have a light-emissive electroluminescent layer including an inorganic semiconductor, such as a Group III-V semiconductor, examples including: gallium nitride; silicon; silicon carbide; and zinc oxide. Throughout this specification, the term “organic light-emitting diode” (herein also referred to as an “OLED”) means: an LED having a light-emissive electroluminescent layer including an organic semiconductor, such as small organic molecules or an organic polymer. It is understood throughout this specification that a semiconductor light-emitting device may include: a non-semiconductor-substrate or a semiconductor-substrate; and may include one or more electrically-conductive contact layers. Further, it is understood throughout this specification that an LED may include a substrate formed of materials such as, for example: silicon carbide; sapphire; gallium nitride; or silicon. It is additionally understood throughout this specification that a semiconductor light-emitting device may have a cathode contact on one side and an anode contact on an opposite side, or may alternatively have both contacts on the same side of the device.

Further background information regarding semiconductor light-emitting devices is provided in the following documents, the entireties of all of which hereby are incorporated by reference herein: U.S. Pat. Nos. 7,564,180; 7,456,499; 7,213,940; 7,095,056; 6,958,497; 6,853,010; 6,791,119; 6,600,175; 6,201,262; 6,187,606; 6,120,600; 5,912,477; 5,739,554; 5,631,190; 5,604,135; 5,523,589; 5,416,342; 5,393,993; 5,359,345; 5,338,944; 5,210,051; 5,027,168; 5,027,168; 4,966,862; and 4,918,497; and U.S. Patent Application Publication Nos. 2014/0225511; 2014/0078715; 2013/0241392; 2009/0184616; 2009/0080185; 2009/0050908; 2009/0050907; 2008/0308825; 2008/0198112; 2008/0179611; 2008/0173884; 2008/0121921; 2008/0012036; 2007/0253209; 2007/0223219; 2007/0170447; 2007/0158668; 2007/0139923; and 2006/0221272.

Throughout this specification, the term “spectral power distribution” means: the emission spectrum of the one or more wavelengths of light emitted by a semiconductor light-emitting device. Throughout this specification, the term “peak wavelength” means: the wavelength where the spectral power distribution of a semiconductor light-emitting device reaches its maximum value as detected by a photo-detector. As an example, an LED may be a source of nearly monochromatic light and may appear to emit light having a single color. Thus, the spectral power distribution of the light emitted by such an LED may be centered about its peak wavelength. As examples, the “width” of the spectral power distribution of an LED may be within a range of between about 10 nanometers and about 30 nanometers, where the width is measured at half the maximum illumination on each side of the emission spectrum. Throughout this specification, the term “full-width-half-maximum” (“FWHM”) means: the full width of the spectral power distribution of a semiconductor light-emitting device measured at half the maximum illumination on each side of its emission spectrum. Throughout this specification, the term “half-width-half-maximum” (“HWHM”) means: half of the full width of a FWHM. Throughout this specification, the term “dominant wavelength” means: the wavelength of monochromatic light that has the same apparent color as the light emitted by a semiconductor light-emitting device, as perceived by the human eye. As an example, since the human eye perceives yellow and green light better than red and blue light, and because the light emitted by a semiconductor light-emitting device may extend across a range of wavelengths, the color perceived (i.e., the dominant wavelength) may differ from the peak wavelength.

Throughout this specification, the term “luminous flux”, also referred to as “luminous power”, means: the measure in lumens of the perceived power of light, being adjusted to reflect the varying sensitivity of the human eye to different wavelengths of light. Throughout this specification, the term “radiant flux” means: the measure of the total power of electromagnetic radiation without being so adjusted. Throughout this specification, the term “central light emission axis” means a direction along which the light emissions of a semiconductor light-emitting device have a greatest radiant flux. It is understood throughout this specification that light emissions “along a central light emission axis” means light emissions that: include light emissions in the directions of the central light emission axis; and may further include light emissions in a plurality of other generally similar directions.

It is understood throughout this specification that “directions along a longitudinal axis” means the directions of the longitudinal axis; and may further include a plurality of other generally similar directions. It is understood throughout this specification that “directions spaced apart from directions along a longitudinal axis” means directions being similar to and spaced apart from the directions along the longitudinal axis.

It is understood throughout this specification that light emissions “along the longitudinal axis” means light emissions that: include light emissions in the directions of the longitudinal axis; and may further include light emissions in a plurality of other generally similar directions. It is understood throughout this specification that light emissions “in directions transverse to the longitudinal axis” means light emissions that: include light emissions in the directions being orthogonal to the longitudinal axis; and may further include light emissions in a plurality of other generally similar directions. It is understood throughout this specification that light emissions “in directions spaced apart from directions along the longitudinal axis” means light emissions in directions being similar to and spaced apart from the directions along the longitudinal axis. It is understood throughout this specification that light emissions “in directions spaced apart from directions transverse to the longitudinal axis” means light emissions in directions being similar to and spaced apart from the directions being transverse to the longitudinal axis.

Throughout this specification, the term “luminescent” means: characterized by absorption of electromagnetic radiation (e.g., visible light, UV light or infrared light) causing the emission of light by, as examples: fluorescence; and phosphorescence.

Throughout this specification, the term “object” means a material article or device. Throughout this specification, the term “surface” means an exterior boundary of an object. Throughout this specification, the term “incident visible light” means visible light that propagates in one or more directions towards a surface. Throughout this specification, the term “reflective surface” means a surface of an object that causes incident visible light, upon reaching the surface, to then propagate in one or more different directions away from the surface without passing through the object. Throughout this specification, the term “planar reflective surface” means a generally flat reflective surface.

Throughout this specification, the term “reflectance” means a fraction of a radiant flux of incident visible light having a specified wavelength that is caused by a reflective surface of an object to propagate in one or more different directions away from the surface without passing through the object. Throughout this specification, the term “reflected light” means the incident visible light that is caused by a reflective surface to propagate in one or more different directions away from the surface without passing through the object. Throughout this specification, the term “Lambertian reflectance” means diffuse reflectance of visible light from a surface, in which the reflected light has uniform radiant flux in all of the propagation directions. Throughout this specification, the term “specular reflectance” means mirror-like reflection of visible light from a surface, in which light from a single incident direction is reflected into a single propagation direction. Throughout this specification, the term “spectrum of reflectance values” means a spectrum of values of fractions of radiant flux of incident visible light, the values corresponding to a spectrum of wavelength values of visible light, that are caused by a reflective surface to propagate in one or more different directions away from the surface without passing through the object. Throughout this specification, the term “transmittance” means a fraction of a radiant flux of incident visible light having a specified wavelength that is permitted by a reflective surface to pass through the object having the reflective surface. Throughout this specification, the term “transmitted light” means the incident visible light that is permitted by a reflective surface to pass through the object having the reflective surface. Throughout this specification, the term “spectrum of transmittance values” means a spectrum of values of fractions of radiant flux of incident visible light, the values corresponding to a spectrum of wavelength values of visible light, that are permitted by a reflective surface to pass through the object having the reflective surface. Throughout this specification, the term “absorbance” means a fraction of a radiant flux of incident visible light having a specified wavelength that is permitted by a reflective surface to pass through the reflective surface and is absorbed by the object having the reflective surface. Throughout this specification, the term “spectrum of absorbance values” means a spectrum of values of fractions of radiant flux of incident visible light, the values corresponding to a spectrum of wavelength values of visible light, that are permitted by a reflective surface to pass through the reflective surface and are absorbed by the object having the reflective surface. Throughout this specification, it is understood that a reflective surface, or an object, may have a spectrum of reflectance values, and a spectrum of transmittance values, and a spectrum of absorbance values. The spectra of reflectance values, absorbance values, and transmittance values of a reflective surface or of an object may be measured, for example, utilizing an ultraviolet-visible-near infrared (UV-VIS-NIR) spectrophotometer. Throughout this specification, the term “visible light reflector” means an object having a reflective surface. In examples, a visible light reflector may be selected as having a reflective surface characterized by light reflections that are more Lambertian than specular.

Throughout this specification, the term “lumiphor” means: a medium that includes one or more luminescent materials being positioned to absorb light that is emitted at a first spectral power distribution by a semiconductor light-emitting device, and to re-emit light at a second spectral power distribution in the visible or ultra violet spectrum being different than the first spectral power distribution, regardless of the delay between absorption and re-emission. Lumiphors may be categorized as being down-converting, i.e., a material that converts photons to a lower energy level (longer wavelength); or up-converting, i.e., a material that converts photons to a higher energy level (shorter wavelength). As examples, a luminescent material may include: a phosphor; a quantum dot; a quantum wire; a quantum well; a photonic nanocrystal; a semiconducting nanoparticle; a scintillator; a lumiphoric ink; a lumiphoric organic dye; a day glow tape; a phosphorescent material; or a fluorescent material. Throughout this specification, the term “quantum material” means any luminescent material that includes: a quantum dot; a quantum wire; or a quantum well. Some quantum materials may absorb and emit light at spectral power distributions having narrow wavelength ranges, for example, wavelength ranges having spectral widths being within ranges of between about 25 nanometers and about 50 nanometers. In examples, two or more different quantum materials may be included in a lumiphor, such that each of the quantum materials may have a spectral power distribution for light emissions that may not overlap with a spectral power distribution for light absorption of any of the one or more other quantum materials. In these examples, cross-absorption of light emissions among the quantum materials of the lumiphor may be minimized. As examples, a lumiphor may include one or more layers or bodies that may contain one or more luminescent materials that each may be: (1) coated or sprayed directly onto an semiconductor light-emitting device; (2) coated or sprayed onto surfaces of a lens or other elements of packaging for an semiconductor light-emitting device; (3) dispersed in a matrix medium; or (4) included within a clear encapsulant (e.g., an epoxy-based or silicone-based curable resin or glass or ceramic) that may be positioned on or over an semiconductor light-emitting device. A lumiphor may include one or multiple types of luminescent materials. Other materials may also be included with a lumiphor such as, for example, fillers, diffusants, colorants, or other materials that may as examples improve the performance of or reduce the overall cost of the lumiphor. In examples where multiple types of luminescent materials may be included in a lumiphor, such materials may, as examples, be mixed together in a single layer or deposited sequentially in successive layers.

Throughout this specification, the term “volumetric lumiphor” means a lumiphor being distributed in an object having a shape including defined exterior surfaces. In some examples, a volumetric lumiphor may be formed by dispersing a lumiphor in a volume of a matrix medium having suitable spectra of visible light transmittance values and visible light absorbance values. As examples, such spectra may be affected by a thickness of the volume of the matrix medium, and by a concentration of the lumiphor being distributed in the volume of the matrix medium. In examples, the matrix medium may have a composition that includes polymers or oligomers of: a polycarbonate; a silicone; an acrylic; a glass; a polystyrene; or a polyester such as polyethylene terephthalate. Throughout this specification, the term “remotely-located lumiphor” means a lumiphor being spaced apart at a distance from and positioned to receive light that is emitted by a semiconductor light-emitting device.

Throughout this specification, the term “light-scattering particles” means small particles formed of a non-luminescent, non-wavelength-converting material. In some examples, a volumetric lumiphor may include light-scattering particles being dispersed in the volume of the matrix medium for causing some of the light emissions having the first spectral power distribution to be scattered within the volumetric lumiphor. As an example, causing some of the light emissions to be so scattered within the matrix medium may cause the luminescent materials in the volumetric lumiphor to absorb more of the light emissions having the first spectral power distribution. In examples, the light-scattering particles may include: rutile titanium dioxide; anatase titanium dioxide; barium sulfate; diamond; alumina; magnesium oxide; calcium titanate; barium titanate; strontium titanate; or barium strontium titanate. In examples, light-scattering particles may have particle sizes being within a range of about 0.01 micron (10 nanometers) and about 2.0 microns (2,000 nanometers).

In some examples, a visible light reflector may be formed by dispersing light-scattering particles having a first index of refraction in a volume of a matrix medium having a second index of refraction being suitably different from the first index of refraction for causing the volume of the matrix medium with the dispersed light-scattering particles to have suitable spectra of reflectance values, transmittance values, and absorbance values for functioning as a visible light reflector. As examples, such spectra may be affected by a thickness of the volume of the matrix medium, and by a concentration of the light-scattering particles being distributed in the volume of the matrix medium, and by physical characteristics of the light-scattering particles such as the particle sizes and shapes, and smoothness or roughness of exterior surfaces of the particles. In an example, the smaller the difference between the first and second indices of refraction, the more light-scattering particles may need to be dispersed in the volume of the matrix medium to achieve a given amount of light-scattering. As examples, the matrix medium for forming a visible light reflector may have a composition that includes polymers or oligomers of: a polycarbonate; a silicone; an acrylic; a glass; a polystyrene; or a polyester such as polyethylene terephthalate. In further examples, the light-scattering particles may include: rutile titanium dioxide; anatase titanium dioxide; barium sulfate; diamond; alumina; magnesium oxide; calcium titanate; barium titanate; strontium titanate; or barium strontium titanate. In other examples, a visible light reflector may include a reflective polymeric or metallized surface formed on a visible light-transmissive polymeric or metallic object such as, for example, a volume of a matrix medium. Additional examples of visible light reflectors may include microcellular foamed polyethylene terephthalate sheets (“MCPET”). Suitable visible light reflectors may be commercially available under the trade names White Optics® and MIRO® from WhiteOptics LLC, 243-G Quigley Blvd., New Castle, Del. 19720 USA. Suitable MCPET visible light reflectors may be commercially available from the Furukawa Electric Co., Ltd., Foamed Products Division, Tokyo, Japan. Additional suitable visible light reflectors may be commercially available from CVI Laser Optics, 200 Dorado Place SE, Albuquerque, N. Mex. 87123 USA.

In some examples, a converging or diverging lens may be formed as a volume of a matrix medium having a suitable shape for functioning as a lens. In further examples, forming a diverging lens may include dispersing light-scattering particles having a first index of refraction in a volume of a matrix medium having a second index of refraction being suitably different from the first index of refraction for causing the volume of the matrix medium with the dispersed light-scattering particles to have suitable light-scattering value for functioning as a diverging lens. As examples, the matrix medium for forming a lens may have a composition that includes polymers or oligomers of: a polycarbonate; a silicone; an acrylic; a glass; a polystyrene; or a polyester such as polyethylene terephthalate. In further examples, the light-scattering particles may include: rutile titanium dioxide; anatase titanium dioxide; barium sulfate; diamond; alumina; magnesium oxide; calcium titanate; barium titanate; strontium titanate; or barium strontium titanate.

In further examples, a volumetric lumiphor and a visible light reflector may be integrally formed. As examples, a volumetric lumiphor and a visible light reflector may be integrally formed in respective layers of a volume of a matrix medium, including a layer of the matrix medium having a dispersed lumiphor, and including another layer of the same or a different matrix medium having light-scattering particles being suitably dispersed for causing the another layer to have suitable spectra of reflectance values, transmittance values, and absorbance values for functioning as the visible light reflector. In other examples, an integrally-formed volumetric lumiphor and visible light reflector may incorporate any of the further examples of variations discussed above as to separately-formed volumetric lumiphors and visible light reflectors.

For example, a lumiphoric ink composition may contain semiconductor nanoparticles. Examples of lumiphoric ink compositions that may be utilized are disclosed in Cao et al., U.S. Patent Application Publication No. 20130221489 published on Aug. 29, 2013, the entirety of which hereby is incorporated herein by reference.

Throughout this specification, the term “white light” means: light having a color point located at a delta(uv) of about equal to or less than 0.006 and having a CCT being within a range of between about 10000K and about 1800K (herein referred to as a “white color point.”). Many different hues of light may be perceived as being “white.” For example, some “white” light, such as light generated by a tungsten filament incandescent lighting device, may appear yellowish in color, while other “white” light, such as light generated by some fluorescent lighting devices, may appear more bluish in color. As examples, white light having a CCT of about 3000K may appear yellowish in color, while white light having a CCT of about equal to or greater than 8000K may appear more bluish in color and may be referred to as “cool” white light. Further, white light having a CCT of between about 2500K and about 4500K may appear reddish or yellowish in color and may be referred to as “warm” white light. “White light” includes light having a spectral power distribution of wavelengths including red, green and blue color points. In an example, a CCT of a lumiphor may be tuned by selecting one or more particular luminescent materials to be included in the lumiphor. For example, light emissions from a semiconductor light-emitting device that includes three separate emitters respectively having red, green and blue color points with an appropriate spectral power distribution may have a white color point. As another example, light perceived as being “white” may be produced by mixing light emissions from a semiconductor light-emitting device having a blue, greenish-blue or purplish-blue color point together with light emissions having a yellow color point being produced by passing some of the light emissions having the blue, greenish-blue or purplish-blue color point through a lumiphor to down-convert them into light emissions having the yellow color point. General background information on systems, devices and processes for generating light perceived as being “white” is provided in “Class A Color Designation for Light Sources Used in General Illumination”, Freyssinier and Rea, J. Light & Vis. Env., Vol. 37, No. 2 & 3 (Nov. 7, 2013, Illuminating Engineering Institute of Japan), pp. 10-14; the entirety of which hereby is incorporated herein by reference.

Throughout this specification, the term “in contact with” means: that a first object, being “in contact with” a second object, is in either direct or indirect contact with the second object. Throughout this specification, the term “in indirect contact with” means: that the first object is not in direct contact with the second object, but instead that there are a plurality of objects (including the first and second objects), and each of the plurality of objects is in direct contact with at least one other of the plurality of objects (e.g., the first and second objects are in a stack and are separated by one or more intervening layers). Throughout this specification, the term “in direct contact with” means: that the first object, which is “in direct contact” with a second object, is touching the second object and there are no intervening objects between at least portions of both the first and second objects.

Throughout this specification, the term “spectrophotometer” means: an apparatus that can measure a light beam's intensity as a function of its wavelength and calculate its total luminous flux.

Throughout this specification, the term “integrating sphere-spectrophotometer” means: a spectrophotometer operationally connected with an integrating sphere. An integrating sphere (also known as an Ulbricht sphere) is an optical component having a hollow spherical cavity with its interior covered with a diffuse white reflective coating, with small holes for entrance and exit ports. Its relevant property is a uniform scattering or diffusing effect. Light rays incident on any point on the inner surface are, by multiple scattering reflections, distributed equally to all other points. The effects of the original direction of light are minimized. An integrating sphere may be thought of as a diffuser which preserves power but destroys spatial information. Another type of integrating sphere that can be utilized is referred to as a focusing or Coblentz sphere. A Coblentz sphere has a mirror-like (specular) inner surface rather than a diffuse inner surface. Light scattered by the interior of an integrating sphere is evenly distributed over all angles. The total power (radiant flux) of a light source can then be measured without inaccuracy caused by the directional characteristics of the source. Background information on integrating sphere-spectrophotometer apparatus is provided in Liu et al., U.S. Pat. No. 7,532,324 issued on May 12, 2009, the entirety of which hereby is incorporated herein by reference. It is understood throughout this specification that color points may be measured, for example, by utilizing a spectrophotometer, such as an integrating sphere-spectrophotometer. The spectra of reflectance values, absorbance values, and transmittance values of a reflective surface or of an object may be measured, for example, utilizing an ultraviolet-visible-near infrared (UV-VIS-NIR) spectrophotometer.

Throughout this specification, the term “lenticular features” means: an array of semicircular convex lenses (“lenticles”) on a surface, being arranged as a sinusoidal series of mutually parallel ridges between troughs, forming a series of “lenticular toroidal lenses.” Background information on lenticular toroidal lenses and lenticular features is provided in Seo U.S. Pat. No. 8,503,083 issued on Aug. 6, 2013, the entirety of which hereby is incorporated herein by reference.

Throughout this specification, the term “microprismatic features” means an array of small, equally-spaced multi-faceted prisms being arranged in a regular array forming a “microprismatic lens” on a surface. Background information on microprismatic lenses is provided in Pakhchyan U.S. Patent Application Publication No. 2011/0292483A1 published on Dec. 1, 2011, the entirety of which hereby is incorporated herein by reference.

Throughout this specification, the term “downward direction” means a direction illustrated as being downward, as indicated by an arrow shown in a Figure herein, being downward relative to an object shown in the Figure. It is understood that the terms “upward direction” and “downward direction” are relative terms defined by the corresponding arrows illustrated in the Figures as indicating such directions; and that the lighting systems illustrated in the Figures may be oriented in other directions.

Throughout this specification, the term “aperture” means an opening in a surface of an object, which forms a cavity in the object, and which may also form a passageway through the object communicating with the opening and with another opening in another surface of the object.

Throughout this specification, the term “ring” means a raised loop on the surface of an object. Throughout this specification, a ring being “configured for being engaged with” another ring means that the ring is shaped to fit together with the another ring, so that the rings may be rotated relative to each other. As an example, the ring may have a surface that is shaped to fit together with another surface of the another ring. In further examples, the ring may have a raised rim with a rim surface being shaped to fit together with another surface that is inside the another ring.

FIGS. 22-24 further show the mounting arm [1802] as including two mounting arm halves [2202], [2204] respectively defining portions [2206], [2208] of the aperture [1804]. In further examples, the example [1800] of the mini-mounting arm assembly may also include: a first mini-bracket [1808] being attached to the mounting arm [1802]; and a first mini-mounting arm [1810] being attached to the first mini-bracket [1808]. As an additional example, the example [1800] of the mini-mounting arm assembly may include a first back plate [1812] being attached to the first mini-mounting arm [1810]. In additional examples, the example [1800] of the mini-mounting arm assembly may include a second mini-bracket [1814], and a third mini-bracket [1816], and a fourth mini-bracket [1818]. As further examples, each of the second, third and fourth mini-brackets [1814], [1816], [1818] may include a mini-mounting arm (not shown) having an attached back plate (not shown), corresponding to the first mini-mounting arm [1810] and the first back plate [1812] being attached to the first mini-bracket [1808]. In an example of the example [1800] of the mini-mounting arm assembly, the first mini-bracket [1808] may be pivotally connected at a pivot axis [2012] by a pivot joint with the first mini-mounting arm [1810]; and the pivot joint may be configured for permitting a range of pivotal movement, as represented by a dashed loop [1824], by the first mini-mounting arm [1810] around the pivot axis [2012] relative to the first mini-bracket [1808]. In another example of the example [1800] of the mini-mounting arm assembly, the second mini-bracket [1814] may be pivotally connected at a pivot axis [2014] by a pivot joint with a second mini-mounting arm (not shown); and the pivot joint may be configured for permitting a range of pivotal movement, as represented by a dashed loop [1826], by the second mini-mounting arm (not shown) around the pivot axis [2014] relative to the second mini-bracket [1814]. In a further example of the example [1800] of the mini-mounting arm assembly, the third mini-bracket [1816] may be pivotally connected at a pivot axis [1904] by a pivot joint with a third mini-mounting arm (not shown); and the pivot joint may be configured for permitting a range of pivotal movement, as represented by a dashed loop [1828], by the third mini-mounting arm (not shown) around the pivot axis [1904] relative to the third mini-bracket [1816].

In some examples, the ranges of pivotal movement [1824], [1826], [1828], [1830] by the first, second, third and fourth mini-mounting arms around the pivot axes [2012], [2014], [1904], [1906] relative to the mini-brackets [1808], [1814], [1816], [1818] being attached to the mounting arm [1802] may collectively constitute a first degree of freedom of the example [1800] of the mini-mounting arm assembly. As another example, the first mini-bracket [1808] being represented by a dashed loop in FIGS. 22-24, may include a first mini-bracket arm [2210] and a first mini-bracket base [2212]. Further, for example, the first mini-bracket arm [2210] may include a ring portion [2002] and the first mini-bracket base [2212] may include another ring portion [2004]. In addition, for example, the ring portion [2002] and the another ring portion [2004] may be shaped for collectively forming a ring [2006] configured for being engaged with a further ring [2214] of the mounting arm half [2202]. Further, for example, the ring [2006] and the further ring [2214] may be mutually positioned for permitting a range of pivotal movement of the first mini-bracket [1808] around another pivot axis [2008], as represented by a dashed loop [2216]. In additional examples of the example [1800] of the mini-mounting arm assembly, the second, third and fourth mini-brackets being respectively represented by dashed loops [1814], [1816], and [1818] in FIGS. 22-24, likewise each independently may include a mini-bracket arm and a mini-bracket base. Further, for example, the second, third and fourth mini-brackets being respectively represented by the dashed loops [1814], [1816], and [1818] in FIGS. 22-24, likewise each independently may have the mini-bracket arm as including a ring portion, and may have the mini-bracket base as including another ring portion. Additionally, for example, the second, third and fourth mini-brackets being respectively represented by the dashed loops [1814], [1816], and [1818] in FIGS. 22-24, likewise each independently may respectively have the ring portion and the another ring portion being shaped for collectively forming a ring [2007], [1819], [1821]; and the rings [2007], [1819], [1821] of the second, third and fourth mini-brackets [1814], [1816], [1818] may likewise be configured for respectively being engaged with further rings [2218], [2302], [2304] of the mounting arm halves [2202], [2204]. In another example of the example [1800] of the mini-mounting arm assembly, the ring [2007] of the second mini-bracket [1814] and the further ring [2218] may be mutually positioned for permitting a range of pivotal movement of the second mini-bracket [1814] around a further pivot axis [2010], as represented by a dashed loop [2220]. In an additional example of the example [1800] of the mini-mounting arm assembly, the ring [1819] of the third mini-bracket [1816] and the further ring [2302] may be mutually positioned for permitting a range of pivotal movement of the third mini-bracket [1816] around an additional pivot axis [1820], as represented by a dashed loop [2306]. In still another example of the example [1800] of the mini-mounting arm assembly, the ring [1821] of the fourth mini-bracket [1818] and the further ring [2304] may be mutually positioned for permitting a range of pivotal movement of the fourth mini-bracket [1818] around a still another pivot axis [1822], as represented by a dashed loop [2308]. In some examples, the ranges of pivotal movement [2216], [2220], [2306], [2308] by the first, second, third and fourth mini brackets [1808], [1814], [1816], [1818] relative to the mounting arm [1802] around the pivot axes [2008], [2010], [1820], [1822] may collectively constitute a second degree of freedom of the example [1800] of the mini-mounting arm assembly. In further examples of the example [1800] of the mini-mounting arm assembly, the ranges of pivotal movement [1824], [1826], [1828], [1830] of the first degree of freedom relative to the mounting arm [1802] by the first, second, third and fourth mini-mounting arms around the pivot axes [2012], [2014], [1904], [1906] may be orthogonal to the ranges of pivotal movement [2216], [2220], [2306], [2308] of the second degree of freedom relative to the mounting arm [1802] by the first, second, third and fourth mini brackets [1808], [1814], [1816], [1818] around the pivot axes [2008], [2010], [1820], [1822]. In further examples of the example [1800] of the mini-mounting arm assembly, the first, second, third and fourth mini brackets [1808], [1814], [1816], [1818] or the first, second, third and fourth mini-mounting arms may have removable set screws or locking bolts (not shown) for fixing the mini-mounting arms at selected positions around the pivot axes [2012], [2014], [1904], [1906]; and the mounting arm [1802] or the first, second, third and fourth mini brackets [1808], [1814], [1816], [1818] may have removable set screws or locking bolts (not shown) for fixing the mini brackets at selected positions around the pivot axes [2008], [2010], [1820], [1822]. In other examples of the example [1800] of the mini-mounting arm assembly, the first, second, third and fourth mini brackets [1808], [1814], [1816], [1818] may have removable set screws or locking bolts (not shown) both for: fixing the mini-mounting arms at selected positions around the pivot axes [2012], [2014], [1904], [1906]; and fixing the mini brackets at selected positions around the pivot axes [2008], [2010], [1820], [1822]. In some examples of the example [1800] of the mini-mounting arm assembly, the first back plate [1812] and the second, third and fourth back plates (not shown) may each independently have an attached housing (not shown) forming a lighting module (not shown) having structures and component parts being analogous to the housings [120], [124], [620], [624], [1120], [1124], [1306], [1314] and the corresponding lighting modules [118], [122], [618], [622], [1118], [1122], [1132], [1148] discussed earlier in connection with the examples [100], [600], [1100] of the lighting system. As further examples of the example [1800] of the mini-mounting arm assembly, the first back plate [1812] and the second, third and fourth back plates (not shown) may each independently have an attached housing (not shown) forming a lighting module (not shown) having structures and component parts being smaller than but otherwise analogous to the housings [120], [124], [620], [624], [1120], [1124], [1306], [1314] and the corresponding lighting modules [118], [122], [618], [622], [1118], [1122], [1132], [1148] discussed earlier in connection with the examples [100], [600], [1100] of the lighting system. In further examples, the mounting arm [1802] of the example [1800] of the mini-mounting arm assembly may replace a mounting arm [226], [228], [726], [728], [1226], [1228], [1326], [1328] of an example [100], [600], [1100] of the lighting system, so that the mounting arm [1802] may have the aperture [1804] replacing an aperture [506], [516], [1604], [1610], [1614], [1622] and with the pivot axis [1902] being oriented along a one of the pivot axes [202], [210], [702], [710], [1202], [1210], [1304], [1312] and may thereby attach the example [1800] of the mini-mounting arm assembly to an example [100], [600], [1100] of the lighting system.
